The light at the end of the tunnel is actually a sense of worth, of value, of relevance... a sense of purpose and place. The loss of these took me here. It is not a light that those in the tunnel control... seemingly forever beyond my reach and unable to believe in value, place or worth. It was never the aim to switch the light off. It was the hand and judgement of others that threw the switch to off. It is why the light and the switch are on the outside of the tunnel and not in the darkness where I am. If you give no worth... If you give no value... If you give no relevance... If you give no purpose... Then there can be no place where the light can shine.
Purpose and relevance feed worth and value... in turn self esteem gets fed. It is false that you must love yourself first. Very definitely it is the other way around.
